obscure ic data needed and online valve/tube data site found

[Peter Blackett]

Hi ,
firstly the good news .
I've found a site that has online valve/tube data available .
http://www.nostalgiaair.org/

getting hold of some valve data quickly has got me out of problems , I
am going to be getting a cd rom with Valve/tube data on it .
The bad news is that I have got given some obscure ic's .......
and I can't yet identify them .
numbers are OMY 125     , omy 120  , omy 122    .
they are in a To5 like can , but with ten legs .
any help in identifying them would be most appreciated .
